5 INTRODUCTION This manual contains instructions, service and installation guidelines for the Single Temp (ST) / Variable Temp (VT) Glassfront Vendor. Please read this manual thoroughly and follow the instructions. The initial set up of a vendor is a very important step of insuring that the equipment operates in a trouble free manner. ST VENDOR/VT VENDOR The ST Vendor is a single zone temperature vendor. All trays are held to a consistent set temperature. The vendor will maintain as low as 2 C (36 F) throughout maintaining health safety for perishable products. The temperature and health safety settings can be adjusted within the control system (see programming manual). The VT Vendor is a two zone/two temperature vendor. This provides for two temperature zones (top and bottom) in a single vendor. The zones are separated by a moveable air deflector and insulating barrier. The vendor has an air duct that runs up the back inner wall of the cabinet. For example: In a 5 tray configured vendor the air deflector and insulating barrier can be moved to provide a refrigerated zone for the bottom two trays while providing a chilled top zone for the top three trays. Positioning of the air deflector and insulating barrier is adjustable in a range of 2 trays in the bottom zone/ 4 trays in the top zone, 3 & 3, or 4 & 2... dependent upon product height and tray spacing. The vending vendor will maintain 2 C (36 F) in the bottom zone while the top zone will be as much as high 19 C (66 F) depending upon ambient conditions. The top compartment can be optionally equipped with a heater & blower system along with a separate temp sensor & relay to maintain a constant and/or higher temperature across varying ambient temperatures. The bottom or single zone has a temperature sensor. The modular insulated refrigeration system draws air across the refrigeration system s evaporator coils up and blows the air up and out of the top of the back duct and which then circulates down through the trays. There are openings in the bottom trays to allow air to circulate around the products. Both vendors will operate within an ambient temperature range of 4 C 32 C (40 F 90 F). AMERICANS WITH DISABILITIES ACT (ADA) Vending operators serving "public entities," meaning government locations and locations accessible to the public, must meet new reach requirements of the law beginning March 15, 2012, under the Americans with Disabilities Act (ADA). The regulations establish side reach regulations requiring that all operable parts of the vending machine be no higher than 48 inches and no lower than 15 inches. This differs from the 1991 standards which have controls at 54 inches high and nine inches low. The Elevator ST/VT fully complies with these regulations. GENERAL All programming (pricing, vend functions and features) is set up within the control system. Changes can be made without any additional accessories or remote parts. Selections can be priced individually from $00.00 to $ in five cent increments (US currency). Cash accountability records, total cash transactions, total vend cycles performed by the vendor, information on individual selections, complete rows or total vendor can be compiled and used for inventory and ordering records. Electrical malfunctions are recorded and displayed when the vending vendor is placed in the Service Mode. Nonfunctional motors or selections are indicated. Each selection has an individual motor. Functional selections will continue to operate if other motors become nonfunctional. The vending sequence is "first in, first out" for each selection, permitting stock rotation to maintain fresh products in the vending area. Elevator ST / VT VENDOR REV E

6 ELEVATOR SYSTEM The elevator mechanism comprises of the following sections: 1) The Elevator Controller 2) The Elevator Frame Assembly 3) The Security Baffle Assembly 4) The Delivery Door Lock Slide 5) The Delivery Door Optical Sensor 1) THE ELEVATOR CONTROLLER (EC) The Elevator Control board is located above the GVC main control board. The EC controls the Elevator & Baffle motor outputs and monitors the inputs associated with the elevator control system, these are as follows: i) Dual Stage Magnetic Encoder (mounted to the Elevator Motor drive shaft) ii) Top Limit Detector (at the top door lock side of the frame) iii) Delivery Door Lock Slide Detectors 1 & 2 (located inside the base of the main door) iv) Delivery Door Open/Closed Optical Sensor iv) Shelf Detect Reed Switch (mounted on the hinge side of the elevator tray) v) Main Door Switch (top hinge side corner of door) vi) Security Baffle Open & Closed Detectors (Top side, front & rear of baffle motor mounting plate) The GVC & EC controllers communicate with each other using the DEX serial bus, the GVC board is the master that issues the various command instructions for the EC controller to execute and report back with a status. See the Elevator schematic circuit in the Appendix. 2) THE ELEVATOR FRAME The welded frame has all the elevator moving parts assembled onto it, comprising: a. The elevator tray with the I vend sensors and shelf sensor. The I Vend sensors detect when a product is successfully dispensed onto the elevator tray and detect when larger items are removed from the elevator tray when in the vend position. The shelf sensor located on the side of the elevator tray detects the shelf position indicators that are adjacent to each shelf. b. The elevator motor & gearbox mounted at the top with a drive pulley fixed to the one side (2 x 5/64 Hex Set Screws) of the output shaft together with an integrated dual magnetic encoder which senses speed & direction. c. The drive axle, one end of which is fixed to the elevator motor output shaft with a coupler (2 x 3/32 Hex Set Screws) the other end has the other drive pulley affixed to it. d. A pair of notched type belts to which the elevator tray is affixed and is driven up & down by the two pulleys at the top. Elevator ST / VT VENDOR REV E

7 e. A pair of plain pulleys, one either side at the base of the frame, the tension of the belt is adjusted by means of the No.8 nyloc nut (11/32 wrench) on the underside of each pulley mount. f. A Top Limit Switch Each time the main door is closed the elevator goes through an initializing routine and the elevator tray actuates the top limit switch at the top of its travel. When the switch is actuated the motor immediately stops and reverses into a downward direction. 3) THE SECURITY BAFFLE Is located in the cabinet under the lower most tray and above the refrigeration module. In principle the security baffle replaces the traditional anti theft flap found in most delivery boxes. Vended items are retrieved directly from the elevator tray, but to prevent additional items being knocked off trays using wires/sticks etc. without paying for them the security baffle closes off access to the cabinet space prior to the delivery door being unlocked. However it is also important to provide free airflow to facilitate good refrigeration performance, hence the security baffle must remain open whilst the machine is in standby sales mode. The security baffle will always be in the closed position when the delivery door is unlocked. The security baffle will remain closed until the delivery door has been locked, which occurs by virtue of the elevator tray being moved to the standby position. 4) THE DELIVERY DOOR LOCK SLIDE The lock slide performs 3 functions: a) Locks/unlocks the delivery door flap. b) Operates Detector Switch 1 (Lower). c) Operates Detector Switch 2 (Upper). The lock slide is operated by the elevator tray, an extension spring will ensure the lock slide returns to the upper position if it is not being pressed down by the underside of the elevator tray. Note: For the sequence of operation see the Appendix at the end of the manual. 5) THE DELIVERY DOOR OPTICAL SENSOR This safety sensor is located above the hinge of the delivery door nearest to the payment system/s. The actuator plate is attached to the door itself and this blocks the optical light path when the door is opened approx. ¼. At any time that the delivery door is open none of the elevator moving part will operate. The delivery door is monitored during the vend cycle to determine whether the delivery door has been opened/closed. If the delivery door is left open for any reason a message will appear on the user display prompting the door to be closed. If an attempt is made to cheat the door the security baffle will immediately be closed and the elevator tray will sent to the vend (delivery door unlocked) position. Should the delivery door be cheated/opened whilst a vend is in progress the system will be rendered out of service and an ELF98 error code will be reported when entering service mode (command out of sequence).

9 UNPACKING This vendor was thoroughly inspected before leaving the factory and the delivering carrier has accepted this vendor as their responsibility. Note any damage or irregularities at the time of delivery and report them to the carrier. Request a written inspection report from the claims inspector to file any claim for damage. File the claim with the carrier (not the manufacturer) within 15 days after receipt of the vending vendor. Carefully remove the outside packing material so as not to damage the finish or exterior of the vending vendor. Inspect the vending vendor for concealed shipping damage. Report any damage hidden by the shipping material directly to the delivering carrier on a hidden damage report. Record the model number and serial number of the vendor for your records. These numbers can be found on the serial plates on the rear of the cabinet and/or inside the vendor. Refer to these numbers in all correspondence and inquiries pertaining to this vendor. Remove the leg covers by removing the screws fastening the covers to the skid boards at all four corners of the vendor. Remove the shipping skids by placing a 2x6 under the vendor, inserting a large screwdriver or prying tool into the grove and splitting it in two. Turn the leveling screws in as far as possible (See Figure 1). INSTALLATION Consult local, state and federal codes and regulations before installing the vendor. Retrieve the keys to the vendor from the coin return cup. Open outer door and remove all internal packing material. Remove leg covers (4) FIG 1. Remove Leg Covers and Skid Boards WARNING: Position and level the vendor prior to connecting vendor to power. All set up steps must be completed prior to prevent harm to the installer or vendor. REMOVING THE DOOR The vendor will fit through most doorways (34"+) by opening the vendor outer door and carefully walking the vendor door or cabinet thorough first and then moving the remaining portion of the vendor through. The vendor outer door may be temporarily removed to permit easier movement through a narrower door openings or hallways. To remove the outer door: 1. Disconnect door harnesses: Loosen the nut and bolt attaching the harness retaining spring to the door harness and unhook the spring from the harness. Unplug the door harness and glass heater harness (option) from the power panel (See Figure 2). Remove harness clamps and cable ties retaining door harness to door. Remove control system cover (see Figure 3) and disconnect door harness plugs from control board. 2. Remove the door: This requires a minimum of two people. Open the door at least 90 degrees. While someone holds the door in place to prevent bending or damage to the bottom pivot, remove the three (3) 5/32" hex socket/allen screws fastening the top hinge assembly to the top of the door (see Figure 4). Once these screws are removed the door needs to be lifted vertically off the bottom hinge. The bottom hinge pin rests on top of nylon washers to provide proper door height and smooth operation retain these washers for reassembly. Disconnect door harness plugs FIG 2.

10 REMOVING THE HINGES AND FRONT LEG MOUNTS The cabinet depth can be narrowed to approximately 31" with the additional removal of the door hinges and front leg mounts. These may be temporarily removed to permit easier movement through a very narrow door openings (32") or narrow/angled hallways. 1. Mark the Door Hinge locations: Mark the location of the top and bottom hinges with a pencil for proper locating upon reassembly. 2. Remove the Top Hinge: Remove the two (2) small locating screws and four (4) large bolts and nuts holding the Top Hinge Plate to the cabinet (See Figure 5). Save the mounting hardware for reassembly. 3. Remove the Front Leg Mounts: From the underside of the cabinet remove the four (4) bolts that secure the front leg mounts. NOTE: Be sure to leave the two inside bolts on each cabinet leg. Pull the leg mounts out forward to remove. (See Figure 6.) 4. Move machine in to final location 5. Reassemble in reverse order 6. Level vendor and check door handle closure FIG 5. Remove Top Hinge Remove these 4 bolts Leave these 2 bolts FIG 6. Remove Leg Mounts POWER CORD INSTALLATION Remove the power cord from inside the vendor. Remove the connection box cover retaining screw and route the cord under the cover. Keep power cord secured on the center back of the cabinet until the vendor is placed into its final location to prevent damage to the cord. INSTALL BACK SCREEN PROTECTOR Remove the screws holding the top screws from the screen on the back of the vendor. Hook the small flange of the Back Screen Protector under the bottom of the screen. Fasten the Back Screen Protector in place with the screen screws removed previously (See Figure 7). FIG 7. Back Screen Protector Installation (hook from bottom, screws at top, airflow up) LEVEL THE VENDOR Position the vendor in its place of operation no farther than nine feet from the power outlet or receptacle. Check that the door will open fully without interference. Leave at least four (4 ) inches of space between the back of the vendor and any wall or obstruction for proper air circulation. All levelers must touch the floor. The vendor must be level for proper operation, cabinet to door alignment, condensate drainage and for acceptance of coins through the coin mechanism. Adjust the four (4) leg levelers on the cabinet legs first to make the cabinet level front to back and left to right. After the cabinet is level adjust the front leg mount levelers to touch the floor surface. The front leg mount levelers should not support for the weight of the cabinet. GROUNDING (EARTHING) & ELECTRICAL Consult local, state, and federal codes and regulations before installing the vendor. Refer to the Safety Installation Guidelines document found in the service package shipped with your vendor. Before connecting the vendor, the integrity of the main electrical supply must be checked for correct polarity, presence of ground (earth) and correct voltage. These checks should be repeated at six month intervals with the routine safety electrical testing of the vendor itself. If the receptacle is not properly grounded or polarized, contact a licensed electrician to correctly polarize and/or ground the receptacle to ensure safe operation. Elevator ST / VT VENDOR REV E

11 For proper operation of any equipment utilizing electronically controlled components, the equipment should be placed on an isolated, or dedicated, noise free circuit properly polarized and grounded. Use of a surge suppressor is recommended for locations where electrical noise is present. MAIN POWER SWITCH Plug the power cord into a dedicated power outlet. Open the vendor door. Turn on the main power switch located on the Power Panel within the cabinet. See Figure 8. DOOR GLASS HEATER HARNESS CONNECTION The Door Glass Heater Harness Connection is normally disconnected to conserve energy. In environments where the humidity is above 70% the Glass Heater Harness should be connected to prevent water condensation from forming on the glass surface. When the ambient conditions are below 70% humidity the glass should be disconnected. See Figure 8. Main Power Switch Door Glass Heater Connection ADVANCED POWER MANAGEMENT The Vendor control system is capable of conserving energy by adjusting time periods and temperature for the refrigeration and lighting. (see programming manual). LOADING PRODUCTS Load products from front to back making sure all items fit freely between the spiral spaces. Do not attempt to force oversize items or packages into the spaces. Do not skip a space. Place the product on the bottom of the compartment on the product spirals with the label facing the front of the vending vendor for easy identification by the customer. See Figure 9. IMPORTANT: No item/product should overhang the front edge of the trays; this will result in a clash with the elevator and will severely affect the machine s performance. SNACK/CANDY/FOOD TRAY OPTION To load products, lift the tray slightly and pull forward until the tray stops. The trays tilt for easier loading. The size of the item being vended must be larger than the diameter of the spiral being used to vend properly. Undersized items could cause vend problems. If the product does not fit the spiral properly, use a different pitched spiral. Call the number located within this manual for spirals available from your distributor or service entity. FIG 9. Loading Products CAN/BOTTLE TRAY OPTION To unlatch the Can/Bottle Trays place both hands with your under palms up then push out simultaneously with your thumbs depressing the slide left and right side latches and pullout as shown (See Fig 10). Carefully load products vertically as shown. Some bottle and/or can containers present and vend better by using the provided spiral risers. If the product requires additional vertical space or presents/vends poorly remove the risers as necessary. Some bottle beverages may require an optional kit for proper vending call the number located within this manual for further information. Pull out the tray to load Push out on latches with thumbs FIG 10. Tray Latches Spiral Risers Elevator ST / VT VENDOR REV E

12 HIGH CAPACITY CAN TRAY (HCCT) OPTION Some vendors come equipped with the HCCT option. There are two setups for the HCCT option one for the vending 355ml (12oz.) and one for 375ml (13oz.) cans. The HCCT option is only provided for these two can sizes with identical diameters. Load product horizontally from front to rear and stack a maximum of three (3) levels high. See Figure 11. Install an empty display can in the areas provided above each selection as shown. Adjust the price scrolls to the desired price. Load cans horizontally up to 3 high as shown Load display cans as shown above each selection FIG 11. High Capacity Can Tray OPTION TRAY ADJUSTMENTS By re timing the spirals, difficult to vend items can be dispensed more dependably. By altering tray spacing, larger items can be vended. By changing the tray configuration, different product mixes can be accommodated. VERTICAL SPACING The trays can be adjusted up or down in half inch increments to provide additional headroom for vending taller products. When increasing the height in one area, the same amount of room will be lost in the tray above or below the one being adjusted. NOTE: Whenever a tray is repositioned (moved up or down) the corresponding magnet/holder must also be realigned with the tray: Food/Snack Tray: The magnet/holder is aligned with the center of the tray base Can & Bottle Tray: The magnet/holder is position one hole above the centerline of the tray base HCCT: The magnet/holder is located on the telescopic slide and moves with it. 5 WIDE FOOD/SNACK/CANDY TRAY REMOVAL AND REPOSITIONING 1.

14 FIG 15. Drawer Slide Removal (Left Shown) CANDY, SNACK, AND MEDIUM (3/4) SNACK TRAY ADJUSTMENTS All of the Snack/Candy/Food/Beverage Trays have adjustable divider locations. By adding, removing, or relocating divider positions a wide variety of selection compartment widths can be obtained as required. (See Figure 16). The dividers can be located in every ½ Candy position. This adjustment provides for CANDY (candy bars, crackers), MEDIUM SNACK (small chip bags, cookies), and full sized SNACK (chips, pastries) width compartments. The divider adjustments also provide for compartments wider than a SNACK compartment width for larger items. Every tray provides motor connections for the maximum number of selections per tray. Additional parts (dividers, motors, spirals, and adapter kits) are available For additional information refer to the Parts & Service portion of the website listed at the beginning and end of this manual. CANDY Width 2-7/8" MEDIUM SNACK Width 4-5/16" Full sized SNACK Width 5-3/4" FIG 16. Divider Positions and Approximate Sizes Elevator ST / VT VENDOR REV E

15 SPIRAL ADJUSTMENT The shape, size and thickness of a product affect how well it falls off the tray. Most products can be vended successfully when the spiral end is positioned at 6 o clock. If vending problems occur with spiral ends at the standard 6 o clock position, adjust the drop off either by retiming the spiral or installing a Product Pusher. SPIRAL TIMING SNACK/CANDY/FOOD TRAY Each spiral can be rotated in 20º (degree) increments for a different drop off point. Most products can be vended successfully when the spiral end is positioned at the position of 6 o clock. The general rule is: The narrower the product, the higher the timing number. Thick Products 3 6 o clock Most products 6 o clock Thin Products 6 8 o clock ADJUST SPIRAL COUNTER CLOCKWISE FOR THICKER PRODUCTS (i.e. 3:00 (0'CLOCK)) ADJUST SPIRAL END POSITION FOR SUCCESFUL VEND. MOST PRODUCTS VEND PROPERLY AT THE 6:00 (0'CLOCK) SETTING SHOWN ABOVE ADJUST SPIRAL CLOCKWISE FOR THINNER PRODUCTS (i.e. 7:00 (0'CLOCK)) IMPORTANT: 1. Ensure the spirals are positioned to prevent the item/product from overhanging the front edge of the tray. 2. Product pushers cannot be used on the ends of the spirals as they will clash with the elevator. TO CHANGE SNACK/CAN/BOTTLE/HCCT SPIRAL TIMING: Each spiral can be rotated in 25 (snack) or 45º (can/bottle) increments for a different drop off point. Most products can be vended successfully when the spiral end is positioned at 6 o clock. 1. Reach behind motor to release spiral coupling from motor. Pinch spiral coupling ends and pull forward on spiral to remove. 2. Rotate the spiral to the desired position and reinsert the spiral coupling into the motor. The spiral coupling must be fully seated into the motor. 3. Test vend to make sure product vends properly. ADJUST SPIRAL END POSITION BY PINCHING SNAP TABS OF SPIRAL COUPLING ON BACK OF MOTOR PULL OUT OF MOTOR THEN SNAP BACK INTO DESIRED POSITION FIG 17: Spiral and Motor Connection MOTOR PAIRING The motor pairing feature facilitates the ganging together of 2 individual motors, so that when a single selection code is entered both motors will operate together; when looking into the machine the LH motor will rotate CCW and the RH motor will rotate CW, the corresponding spirals also have to be CCW & CW. This feature allows the 2 motors to be spread apart from each other to suit the width of the item to be vended. The selection width can be as little as 5 ¾ wide (standard snack width) e.g. ganging selection motors 46 & 47 together, or the paired motors/spirals can span the entire width of the shelf e.g. ganging selection motors 40 & 49. The 2 paired motors have to be wired up in accordance with the physical span between them. See the SERVICE MODE section 7.0 for the programming instructions for setting up paired motors. Note: the 1 st motor should always be an even number, the 2 nd motor must be odd. Elevator ST / VT VENDOR REV E

16 PROCEDURE FOR INSTALLING A COIN CHANGER 1. Mount the changer unit onto the 3 screws provided (see fig.1a) and then secure. NOTE: Most units should be mounted using the center set of holes. Check the alignment between the coin entry chute and the entry hopper on the unit to determine the best alignment, use the LH or RH mounting holes if needed. 2. Check the relationship between the underside of the coin changer and the top surface of the coin cup area, ensure there is clearance of approximately 3/16 between them; pull/push the coin unit out/in several times to ensure there is no interference between the underside of the coin mechanism and the coin cup deflector. Adjust the coin unit mounting assembly up/down by slackening/tightening the nuts shown in fig.1b. 3. Check the relationship between the underside of the coin entry chute and the top surface of the coin entry hopper to ensure there is minimum clearance between them. Insert the largest and smallest physical coins to verify there is clear passage. Adjust the coin entry chute up/down by slackening/tightening the nuts shown in fig.2. Also consider the adjustment in Step 1 which may provide a better solution. 4. With the machine switched ON and the coin changer housing pushed firmly home, push the coin return button to check the operation of the coin return motor (see fig.2). ensure that the reject lever on the coin mechanism is actuated sufficiently to clear bent coins, if the stroke of the coin return crank arm needs to be increased/decreased, adjust by slackening/tightening the screws shown in fig.3. fig.2 COIN RETURN SWITCH fig.3 a fig.4 b PULL TAB fig.5 fig.1 RETAINING LUG CASH BOX 1. To remove the cash box tilt the box slightly upwards (see fig.4) at the front to disengage it from the retaining lug on the floor (see fig.5) of the housing before attempting to slide it out. 2. When returning the cash box again tilt it slightly upwards at the front and when pushed full in allow the cash box to sit down and ensure the retaining lug has engaged by pulling/tugging on the box without lifting. IMPORTANT: 1. Ensure that the coin unit is pushed fully home after servicing, a positive click will be felt when this is achieved. Failure to do this will result in coins becoming jammed etc. 2. DO NOT attempt to close the main door whilst the coin unit is pulled out. 3. Ensure that the cash box is located fully into its housing before closing the main door Elevator ST / VT VENDOR REV E

17 LOADING THE COIN MECHANISM The Coin Mechanism must be loaded with some level of each coin for change in order for the vendor to operate properly. The coins need to be loaded into the coin mechanism by inserting into the front coin insert. First enter the SERVICE MODE then the TUBE FILL MODE (See SERVICE MODE instructions COIN/TUBE FILL MODE). PRESS SERVICE MODE BUTTON AND ENTER TUBE FILL MODE (PRESS 1) INSERT COINS THROUGH FRONT DOOR COIN INSERT TO FILL COIN TUBES Make sure to load the correct coins into their correct tubes. Each tube should be kept loaded with at least one roll of each coin to keep above the tube low level sensors. Once the tubes are loaded to these levels the Dollar Bill Validator will accept bills. If the coin tubes fall below this level the Dollar Bill Validator may stop accepting bills and the front display will indicate "EXACT CHANGE ONLY". Alternatively, the coins can be manually loaded into the slots above the respective coin tubes; however this is not the recommended method. IMPORTANT: It is highly recommended to utilize the TUBE FILL mode to be sure that the control board can accurately determine coin counts/levels to avoid Exact Change conditions e.g. no bill acceptance On some Coin Mechanisms there are buttons above each tube to dispense the coins (may vary depending on which coin mechanism that is used). The coins can also be dispensed within the Service Mode described later.

18 VEND CYCLE IVEND EQUIPPED All vendor selections have been assigned at the factory to be monitored for ivend optical sensing. At the start of a vend, the ivend optical sensor will be checked to make sure it is not blocked, damaged or disconnected. If blocked, damaged or disconnected the elevator will not be able to move, I Vend must be operational for the Elevator to function. The vend motor and a vend timeout timer are started: The selection motor/s rotate/s a full turn (360 ) to the home switch position. If a product is detected passing onto the elevator the vend is considered successful. If reaching the home switch position and a product has not been detected, then the vend motor will pause for 1 second while the controller continues to monitor the optical sensor for product delivery and then: o If a product is detected during this pause the vend is considered successful. o If a product is not detected, then the controller initiates a second motor cycle while continuing to monitor the optical sensor. If a product is detected during this second cycle, the motor will be stopped immediately. The vend is considered successful. The 2ND VEND accounting counter is increased by one. If after reaching the home switch position and a product has not been detected, then the vend motor is stopped and for 2 seconds the controller continues to monitor the optical sensor for product delivery. If a product is detected, the vend is considered successful. The 2ND VEND accounting counter is increased by one. Otherwise, if no product is detected, the selection is logged as sold out. Such a state will trigger to display the MAKE ANOTHER SELECTION message. The original credit remains and is displayed, the customer can press selection buttons to activate this or another motor or press the coin return button. o If after 10 seconds there is no home switch signal and no product is detected, then the vend is failed. The vend motor is shut down and MAKE ANOTHER SELECTION is displayed. The customer can press selection buttons to activate another motor or press the coin return button. NOTE: In this case Force Vend (if enabled) is disabled to permit the customer to retrieve the deposited money. SALES MODE The vendor automatically defaults to Sales Mode after it is turned on. In the Sales Mode, the vendor accepts money deposits, pays out change and dispenses product to the customer. DISPLAY CREDIT ELECTRONIC PRICING This vendor is equipped with the Electronic Pricing feature. The customer may verify the price by pressing the selection number (i.e. 22) before inserting money. If a selection is made and credit has not been established, the price for that selection is displayed and INSERT MORE MONEY will be displayed. When money or credit is accepted, then the amount of credit is displayed. "USE EXACT CHANGE ONLY" MESSAGE OPERATION If the coin levels in the coin mechanism tubes are below the low level sensors, USE EXACT CHANGE ONLY will be displayed. This indicates the Coin Mechanism does not have enough coins in the coin mech tubes to make change. This also indicates that the Dollar Bill Validator may be disabled until change can be made.

25 TEMPERATURE CONTROL NOTE: To prevent damage to the refrigeration compressor when it is turned OFF or if the power is interrupted, the unit will not be switched back ON regardless of temperature for at least 3 minutes to allow the internal pressure to drop. REFRIGERATION SENSORS The temperature sensor(s) is/are positioned to best represent the product temperature and is/are monitored by the control system. The refrigeration system is activated depending on the target temperature setting or SET POINT. The total allowable temperature variation from the SET POINT is DELTA. SENSOR1 Single Zone versions have SENSOR1 located near the top right of the vendor cabinet assembly. Dual Zone versions have SENSOR1 located under the dual zone barrier on the right side of the cabinet assembly. SENSOR2 Dual Zone versions may have an optional SENSOR2 mounted near the top right of the vendor cabinet assembly. RELAYS The control system controls up to three relays which then control the refrigeration and heating systems: RELAY1: Controls the compressor and the condenser fan (refrigeration system). RELAY2: Controls the evaporator fan (refrigeration system). RELAY3 OPTION: Controls the optional upper zone blower and heater system. DOOR SWITCH The door switch is located in the upper right corner of the vendor door assembly (See Figure 20). The door switch is monitored by the GVC control system and the Elevator Controller for evaluating when to run the refrigeration/evaporator systems, when to reset optional health safety and when to reset the elevator to check all is clear after filling and to learn the tray positions which may have been moved). If the Vendor is plugged in and the power switch is on and the door is open, then the compressor, evaporator fan, heater and heater fan are all turned off. A 30 minute door timer starts and a compressor delay timer starts. If the door is open for more than 30 minutes, the controller will resume closed door operation, the message DOOR ALERT is displayed and error code is set. If the door is closed, then evaporator fan is turned on. When the compressor delay timer expires, then the controller evaluates the zone sensor readings, relay states and timers. Door Switch FIG 20.

The evaporator is located between the lowest tray and the compressor. The evaporator fan distributes cold air to products in the bottom zone. The refrigeration compressor is fully insulated and is located below the bottom tray. CUT IN The refrigeration system is turned on when the temperature reading of SENSOR1 is greater than or equal to SET POINT plus half of DELTA. CUT OUT The refrigeration system is turned off when the temperature reading of SENSOR1 is less than or equal to SET POINT minus half of DELTA. HEALTH SAFETY The HEALTH SAFETY feature prevents the sale of perishable food if the air temperature inside the bottom zone (SENSOR1) rises above the health safety temperature limits for cold food products (41 F / 5 C) for more than 15 minutes. The SZF/DZF Vendor can vend cold food products that require storage temperatures in the range of 32 F to 41 F. NOTE: After filing the machine the health alarm is overridden for 30 minutes following the door closure WARNING: The operator is responsible for enabling the health safety alarm for perishable products. Check local codes to see which products require the protection of the health safety alarm. Refer to the CONTROL SYSTEM Programming Manual for additional instructions on how to set the Health Safety and Health Safety Range. Elevator ST / VT VENDOR REV E

27 HEALTH SAFETY (HS) TEST The HEALTH SAFETY feature prevents the sale of perishable food if the air temperature inside the food compartment rises above the Health Safety temperature limit for more than 15 minutes. The factory default for health safety limit is automatically set when the refrigeration configuration is set. The perishable products being vended must match the refrigeration configuration. Important Note: Make sure that the Health Safety setting is enabled prior to starting this test. See Service Mode below. 1. Simulate a Warm Temperature a. Open the door b. Locate the sensor towards the back of the cabinet at the right side of the top tray. c. Remove the mounting screw; place the sensor in a vessel/cup of warm water. d. Enable HS Test software setting in control board service mode see below. e. Close the door. 2. Perform Test a. Press on the host machine numerical keypad to check the temperature. b. Wait until the temperature is above the upper health safety limit of 41ºF for 15 minutes. c. Attempt to vend a product from the machine that you know is protected by health safety (see menu 4.9.1). d. If the health safety is working properly the vend should fail; the machine should have automatically been disabled by the controller board. 3. After Test is Completed a. Remove the sensor from the cup of water and put the sensor back in place. HS TEST SOFTWARE SETTING Service Mode When HS test ON (HS Door switch override ON) is saved in Service mode, and the machine door is closed the Health Safety Activation Delay Time is set to 15 minutes (Door Closed Operation) rather than the extended 30 minutes that is allowed after a door closure due to service or product refill. To allow for possible multiple door open/close cycles the HS test mode is active starting 3 minutes after "HS test ON" is set in Service Mode. Once the door is closed Health Safety feature now functions as if the machine door had been closed for a long period of time and any temperature value over the HS limit, for the refrigeration mode in use. The 15 minute HS limit timer starts a count and if the temperature limit is exceeded for 15 minutes it disables vending from the machine.
